y My invention'relates to oil burners of the type patented in Letters Patent #1,529,821 to Myron lVlVood.'k y *Y Y v f I am the assignee of Ysaid patent. andmy present inventionhas foriits object to improve ,Y upon the structure disclosed in said patent. l

More specifically, it isiny purposey to improveupon the vaporizingportion Vof the. y structure, wherebythe cost offuel may. be 1Q .reduced approximately10% r oyerthat of ex- A y isting types of burners. ,l

'A furthel1 Objectis to provide a burner having the flame dividing lugs of the 1before mentioned; application, the flangewhiclil car 15 yries said lugs being divided so as to lfacilitate Y lthe assembling ofthel burners in a furnace and the lugsof theV outer .portion o-f theflange serving .notj only yin their flame ,dividing Vcapacity but also asa means for supporting the 20 outer yportion-ofthe flange upon the inner Y portion thereof. V

A' Y With theSe and other robjects in view, my

invention consistslin the construction, ar-

' rangementand'combination ofthe various y Vparts lof my device, whereby the objects .con-

v templat'ed are attained, ashereinafter more fully set fo-rth, pointed out in my claims, and

" illustrated in the accompanying drawings, 1nA

whichz' tionalview through the burner of the present invention, Y

Fig. 2 is a'planview lof thesame,a part of the flame spreading hood being removed4 upper surface of to disclose the construction therebeneath.

. `Fig.. 3 is van enlargement 'of a portion of Fig. 1. f

I'h'ave used the reference character 10 tol indicate generally the skirt orflue upon which the burn-erY is supported land whichfserves to provide a closed draft through the grates of a furnace to the burner proper. A Y f y n e The latter includesfan outer, cylindrical Vwall11, having a slightly reduced. neck 12 '45 at its lower extremity, forming-.a shoulder 13 to seat upon the skirtk 10.y An intermediate wall 14 is formed integrally with `the wall 11'vand connected theretoby a bottom wall'15, y.. S which extends' inwardly beyond thewall14 and thence upwardly as at 16 toform an, Over-l Fig. :1 is'a vertical, transverse, central, sec- Y flow well 17. The space between the walls 11 and 14 forms'the vaporizing well 18. .y

A flame directing iiange 19 is formed inte- `rally withthe wall 11 and extends upwardlyl 4 and outwardly from l the Yupper extremity thereof, above the top of the ywall 14, wherebyy overflow oily will .pass overthe wall 14 into the overiowwell 17.V l, f e l f l Flame spread'ngjlugs 21 are formed integrally with the flange 19.,

space encircledbyA the wall 14 and over andbe- Vyond the wall14 torabout the positionshown in Fig. vThreefverticalffnis,` 22,'for1nedl integrally lwith the -hood 21, are shouldered,

las at 23, to'rest upon .and within the wall 16.

Y rlhe parts Just described are substantially the same as in the prior patent hereinbefore referred to. Y f c 1 find that by leaving thewell o-pen above the liquid, that a greater percentage of vaporization will take placewithin the well itself. y

The heatfromthe'flame is carried by conduction through the walllltofthe walls ofthe well18 and vaporizati'on will take place with inthe well, the gases rising to the top ofthey well to be burned. y I find thatamore perfect vflame vis obtainedjwhere the top of the well j is covered by a ring suchas'the ring 24 provided with burneropenings 25. vThe-ring 24 is inclined at Vabout the same angle as the iange 19 andis Aprovided with a substantially horizontal flange 26,'wliich restswithin an annular seat 27 ,v formed inthe wall 11. The v the ring 24 is substantially flush with theupper surface'of the flange 19.

. The ring is thickened between the walls 14 and 11 so lasto forma shoulderk 28 which lits snugly against the inner surface of the wall 11. The inner extremity of the ring is pro-` 91) I videdfwith a vertical iiange'29, which receives the .wall 14 and is' sealed thereagainst Y by means of cement 3,0.v The seating of the v lshoulder' 28 and the flange 27 effectively seals the wellagainst the escape of gas` except 95.

` throughthe openings 25 without interfering v Y i with the expansion of the parts relative to eachother..V j l l vThe gas will therefore issue through the openings 25 An air spreading hood 21 extends i'ntofthev en@ l0@ burned above the burner. 190 *i ring in a flame which spreads outwardly and upwardly over the flanges 19. The air current directed downwardly against the ring by eddy currents interfering with the..srnoothaction of the burner. ,The smooth flowing of the air currents results in more perfect combustion and higher efficiency of openation. The vaporization within theV well 18 is greatly enhanced byrthejiusefoffaerelatively tightly woven wick 3l in the formV of a cy- -lindrical- Sleeve encircling the wall 14 and; fitting snuglythereagainst. The wick takes -up only-asmall portion ofthe spaceof the well. Itrests at its lower end upon the botv. tomwa'll 1:5;an`d at its upper-end within the space between the flangei29 `and thewallllff.

The wiek'l servesto carrythe-oil from the i 1 bottomv ofthe well T118 upwardly against the `saine y angle.

1 heated wall 14 andi/provides a' largeV surface for radiation of thevaporized-oil ntothe surrounding space.
